:''See also Havannah, Cheshire, a place near Congleton in Cheshire, England. Havannah is an abstract strategy board game invented by Christian Freeling. It is best played on a base-10 hexagonal board, ten hexes (cells) to a side. Havannah belongs to the family of games commonly called connection games; its relatives include Hex and TwixT. The game was published for a period in Germany by Ravensburger (the Ravensburger edition, however, had a smaller, base-8 board). It is nowadays only produced by Hexboards.〔(Hexboards )〕 ==Game rules== One player plays as Black; the other plays as White. White starts, after which moves alternate. The rules are as follows: *Each player places one stone of their color on the board per turn. *Stones are never moved, captured, or otherwise changed. *A player wins when they complete one of three different structures from unbroken lines, or paths, of connected stones, all of their colour: * *A ''ring'' is a loop around one or more cells (no matter whether the encircled cells are occupied by any player or empty〔As clarified by Freeling at http://www.mindsports.nl/index.php/arena/havannah/49-havannah-rules; Schmittberger's book wrongly states that a ring should surround at least one vacant cell.〕); * *A ''bridge'', which connects any two of the six corner cells of the board; or * *A ''fork'', which connects any three edges of the board; corner points are not considered parts of an edge. An example of all three winning combinations is shown at right. The structure in the centre of the board is a ring; the structure on the left-hand side is a fork; the structure on the right-hand side is a bridge. Since the first player to move in Havannah has a distinct advantage, the pie rule is generally implemented for fairness. This rule allows the second player to choose whether to switch positions with the first player after the first player makes the first move. Players of different strength can still play an interesting game when the weaker player (as White) is allowed to place two or more stones on the first turn. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Havannah」の詳細全文を読む スポンサード リンク
